Background to my question:
I'm currently in the process of investigating the usual electronic problems with the Minolta X cameras with focus on the Minolta X-700.
Unfortunately, it is not always the electrolytic capacitors that turn off the LEDs or prevent the shutter from opening. According to the documents available to me (SPT Journal, C & C Associates Electronic Troubleshooting Guide, Service Manual, Camera Craftsman), I suspect problems with the magnets or defective ICs.
I am therefore interested in whether such topics are discussed in the Facebook group, including a theoretical background (cause of the problems).
In my experience, it is difficult to find information on such issues in the Web.
